Not all species that are aquatic use external fertalization. Dolphins se internal fertilization but it is very dificult because they would have to evolve adapted sexual organs and i dont think fishes have the right organs for internal fertalizations so they juust eject it into water. I'm not sure this is correct but i hope it helps. You might nneed to check it before you use it in any peices of writing.

External fertilization in animals?
External fertilization occurs when the union of egg and sperm takes place outside the bodies of the individuals involved. It is common in aquatic animals such as fish and amphibians, where both gametes are released into the water for fertilization to occur. This type of fertilization is less reliable than internal fertilization as it is subject to environmental factors such as water currents and predation.
What are the similarities of internal external fertilization?
Both internal and external fertilization involve the joining of sperm and egg to form a zygote. In both processes, the end result is the fertilization of an egg. The main difference lies in where the fertilization occurs - internally within the female's body or externally in the environment.
What relationship exists between an organisms habitat and its method of fertilization?
The organism's habitat can influence its method of fertilization based on the physical conditions required for successful reproduction. For example, in aquatic environments, external fertilization is common among species that release gametes into the water for fertilization to occur. On the other hand, in terrestrial environments, internal fertilization is more prevalent to ensure protection of gametes from drying out.
Are all eggs fertilized in external fertilization?
No, in external fertilization, not all eggs are fertilized. The eggs are released into the environment and must be externally fertilized by sperm for fertilization to occur. Many eggs may not encounter sperm and therefore will remain unfertilized.
Where does fertilization occur in a female sheep?
In the fallopian tube and uterus.
What adaptations in aquatic animals help ensure that external fertilization will occur?
produce more eggs
What type of fertilization and development occur in the zebrafish?
Zebrafish exhibit external fertilization, where the female releases eggs and the male fertilizes them outside of the body. The embryos develop externally, with the early stages of development taking place outside of the mother's body in the water.
External fertilization in animals?
External fertilization occurs when the union of egg and sperm takes place outside the bodies of the individuals involved. It is common in aquatic animals such as fish and amphibians, where both gametes are released into the water for fertilization to occur. This type of fertilization is less reliable than internal fertilization as it is subject to environmental factors such as water currents and predation.
What are some environments in which external fertilization can occur?
Water would be the number one choice.
What is the difference between external fertilization and internal fertilization?
External fertilization occurs outside of the female's body, typically in water, where eggs and sperm are released for fertilization to occur. Internal fertilization, on the other hand, happens inside the female's body where sperm is deposited directly into the female reproductive tract to fertilize the egg.
What are the similarities of internal external fertilization?
Both internal and external fertilization involve the joining of sperm and egg to form a zygote. In both processes, the end result is the fertilization of an egg. The main difference lies in where the fertilization occurs - internally within the female's body or externally in the environment.
Can it be possible for fertilization to happen outside the female human body?
Fertilization that happens outside the female body is called in-vitro fertilization. In this procedure, the ova is fertilized with the sperm in a laboratory.
When does fertilization in mitosis occur?
Fertilization in mitosis occurs when the sperm and egg cells fuse during sexual reproduction, typically in the reproductive organs of plants and animals. This fusion of gametes results in the formation of a zygote, which then undergoes mitotic cell division to develop into a new organism.
What relationship exists between an organisms habitat and its method of fertilization?
The organism's habitat can influence its method of fertilization based on the physical conditions required for successful reproduction. For example, in aquatic environments, external fertilization is common among species that release gametes into the water for fertilization to occur. On the other hand, in terrestrial environments, internal fertilization is more prevalent to ensure protection of gametes from drying out.
Where and when does fertilization occur?
Fallopian Tubes
Where does fertilization occur in a plant?
ovary
Does sexual life cycles differ with respect to the relative timing of meiosis and fertilization?
Yes, sexual life cycles can differ based on the relative timing of meiosis and fertilization. In some organisms, such as animals, meiosis and fertilization occur separately and alternately, resulting in a diploid-dominant life cycle. In contrast, in some algae and fungi, meiosis and fertilization can occur in close succession, leading to a haploid-dominant life cycle.
